Part A

Mathematics
1 answer:
N76 [4]3 years ago
5 0

Step-by-step explanation:

Part A: We can write 40 + x + 25 = 180 because these angles are supplementary, meaning they add up to 180 degrees, and when we solve for x, we get x = 115°.

Part B: We can write y = x + 25 because these two angles are vertical angles, meaning they are equal and formed from the same lines. We know that x = 115°, so when we plug that in we get y = 140°.

Part C: z = 40° because these two angles are vertical angles. I hope this helps!

On the other hand, winning the lotto is 1 chance in 13,000,000 which if you've ever played the lotto you know that those odds are good enough to insure that if you played for the rest of your life and you are 18 not expect to live to 80 and you have 104 [given 2 draw a week] chances of winning per year, it likely won't happen. One in 1200 is better but still not good, especially with only 1 draw.

The diagram shows a plan for the rectangular house with an attached porch. The combined area of the house and the porch is 733ft
Nikolay [14]

The value of x in the diagram is 8 feet that makes the combined area of the house and the porch to be 733 ft²

<h3>How to calculate area?</h3>

Combined area = big rectangle + smaller rectangle - triangle

Hence:

733 = (13 * (59 - x)) + (x * 9) - 0.5(9 - 7) * (x - 6)

733 = 767 - 13x + 9x - x + 6

x = 8 feet

The value of x in the diagram is 8 feet that makes the combined area of the house and the porch to be 733 ft²

A father is 25 years old . Six years ago he was 5 times as old as his son. Find the present age of Father and son.​
raketka [301]

Answer:

Define F as fathers age and S as sons age right now.

Then now they are

(1) 3S = F

and six years ago they were

(2) 5*(S-6) = F-6

calculate 5*(S-6)

5S - 30 = F-6

Subtract left and right side by -F

Add 30 to left and right side

5S - F = 24

Put (2) 3S = F into the equation above

5S - 3S = 24

2S = 24

S = 12

insert result in (2) 3S = F

3*12 = F

36 = F

Step-by-step explanation:

So the son is 12 years, and the father is 36 years.
